These tests are NOT proof of
They only go back 3-5 generations. These tests are being used by scammers to "prove" that their off standard dogs "are purebred"
Scammers in many breeds
including Rottweilers, are adding a different breed to obtain a color
or trait they want (merle or red for example) then breeding those
to the target breed for 5+ generations (all the while lying on
registration paperwork and commiting stud book integrity fraud).
Then they will Embark (or
other breed dna test) the dogs to claim they
DO NOT BE FOOLED!
Do not get scammed into paying more
In general the
"theory" that red/tan (and maybe blue/tan) Rottweilers
"could" exist sounds valid. because Rottweilers and Greater Swiss
Dogs are very
closely related and blue/tan and red/tan occurs with frequency in a few
lines of GSMD. HOWEVER the reality is that since the mid 1900's the
Rottweiler has been bred solely for black/tan discarding all other base
colors including wolf sable and brindle. That said it is "possible"
that some older
lines "could" harbor the recessive blue/tan or red/tan (but NOT wolf
sable or brindle
as they are a dominant) , however it is HIGHLY unlikly.
is DNA proof (DNA parentage NOT Embark type test) of *the parentage of
the litter AND *the parent's parents AND *parent's grandparents and so
on for more than 5 generations, then
the pups are more likely mixes between Rottweilers and Doberman or
breed where those recessive colors are far more common.
In almost 40 years in the breed dealing with both US and Euro/import lines I can tell you that I have seen/heard of exactly FOUR supposed purebred red/tan, ONE blue/tan and one black pigmented white. That is it, AND all were before DNA parentage was commonplace so there's still doubt!
Both parents would
have to carry the gene
for it to appear.
Off color coated dogs should never be bred as these colors were removed from the breed towards the beginning of the breed history.
Dogs affected with
Vitiligo are NOT blue merle.
gene exists in the breed, nor EVER did.
IF you see a merle
Rottweiler is IS NOT purebred
Dogs with vitiligo (as in humans) have an autoimmune disorder that affecteds the pigment cells.
The only Breed standard accepted color in
any country is black with
tan, rust, brown or mahogany markings
*Long coat is a disqualifying fault
(note-test your breeding dogs only at a lab that tests for all 5 long genes- most labs only test for L1 and some rottweilers have a different long coat gene)
*Wire to the extent that it changes body coat is a disqualifying fault (tiny slight beard is not)
>*Any base color other than black is a disqualifying fault
*Blue eyes are a disqualifying fault and very uncommon
*Total Lack of markings is a disqualifying fault
*White marking beyond few white hairs on chest is serious fault
*Merle does not and never has existed in breed
The below historical information is
derived from several old breed standard and history sources including
“Studies in the breed history of the Rottweiler”
Many breeds have color specific standards
Rottweilers are just one example
The breed started life with many colors :
*Wolf sable (agouti) with tan points
*Brindle on ash grey background with tan points
*Black and tan (black tan point)
*Red and tan (brown tan point)
*The breed nearly died out and was rebuilt wherein some yellow (ee) and sable (ayat) dogs popped up from mixed breedings
*All of the above colors occasionally with white chest and belly markings
The breed clubs decided they only wanted black and tan with no white so started editing the standard over several years.
In the 1901 standard the first colors to be eliminated were yellow/red dogs with no tan points (ee- recessive red or ayat sable) because they were thought to be strong indicators of mixed breedings. The standard still listed both brindle on ash grey background and wolf sable(agouti) and red with tan points (brown tan point) in addition to black with tan, rust, brown or mahogany markings (black tan point ).
The 1913 standard dropped brindle and
wolf sable, but red with tan points (brown tan point) remained.
In 1921 the two Rottweiler clubs in
existence combined to form the ADRK and the first ADRK standard only
allowed black with
tan, rust, brown or mahogany markings dogs, but some white on chest and
belly was allowed but undesirable
After 2nd world war the standard was redone again and the only allowed color was black with tan, rust, brown or mahogany markings dogs with any white being undesirable
Modern Rottweilers genetically are
for all intents and purposes, entirely clear of anything
but black with
tan, rust, brown or mahogany markings
(black tan point genetically BBatat)

Wolfsable is absolutely totally gone, if you see it it’s a mix (genetically this is agouti with tan points)
Brody was a Rottweiler X German Shepherd
Ash grey striped dogs (brindle on a pale
grey base) are absolutely totally gone, if you see one, it’s a
The yellow/red colored dogs (ee recessive red or ayat sable) also long gone if you see a red no tan point dog it it’s a 1000% mixbreed in spite of internet sites that want you to believe differently

Red &tan (brown tan point) has been
bred out so much that if you
see one, assume the dog is a mix breed unless the owner has many many
parentage dna verified (not breed dna tests) as scam breeders have been
mixing in red & tan Dobermans to sell the pups as rare red
likly purebred- before color
testing was available

White markings have been mostly bred down to just a strip or few hairs at most on the chest.
